Definitions
- a replacement of the platinum feed pipe that is dipped from above into the melt by pipes of other materials, such as ceramic or silica glass, does not result in a permanent solution of the problem, since all materials dissolve in a few hours in the aggressive melts and thus are not suitable for continuous glass production.
